Apple Pencil 0% battery and won't charge

I'm using iPad pro with Apple Pencil for drawing daily, and I noticed my Apple Pencil stopped working today.

I plugged the pencil into the charger and on iPad widget it shows that there is 0% battery left and the charge lightening bolt shows up. Charge for 30 minutes the battery is still at 0%. Unplugging the pencil from the charger the pencil immediately disappears from the widget. The same happens if I plug the pencil into the iPad port.

I've tried hard rebooting my iPad, re-pairing the pencil, but still the pencil only shows up in the widgets displaying 0% battery and the charge lightening icon, and unplugging the pencil from the charger / iPad disconnects the pencil from the iPad immediately, no matter the duration of the charge.

Has anyone had the same experience before?
